kubernetes k8s.gcr.io拉取镜像失败问题

kubeadm init默认用的是k8s.gcr.io这个仓库,由于国内被屏蔽了
搜了很多文章都是用脚本去解决，这个太繁琐了。
最后kubeadm init --help看了一下，发现其实可以指定image的仓库。

Flags:
      --apiserver-advertise-address string   The IP address the API Server will advertise it's listening on. If not set the default network interface will be used.
      --apiserver-bind-port int32            Port for the API Server to bind to. (default 6443)
      --apiserver-cert-extra-sans strings    Optional extra Subject Alternative Names (SANs) to use for the API Server serving certificate. Can be both IP addresses and DNS names.
      --cert-dir string                      The path where to save and store the certificates. (default "/etc/kubernetes/pki")
      --certificate-key string               Key used to encrypt the control-plane certificates in the kubeadm-certs Secret.
      --config string                        Path to a kubeadm configuration file.
      --control-plane-endpoint string        Specify a stable IP address or DNS name for the control plane.
      --cri-socket string                    Path to the CRI socket to connect. If empty kubeadm will try to auto-detect this value; use this option only if you have more than one CRI installed or if you have non-standard CRI socket.
      --dry-run                              Don't apply any changes; just output what would be done.
  -k, --experimental-kustomize string        The path where kustomize patches for static pod manifests are stored.
      --feature-gates string                 A set of key=value pairs that describe feature gates for various features. Options are:
                                             IPv6DualStack=true|false (ALPHA - default=false)
  -h, --help                                 help for init
      --ignore-preflight-errors strings      A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks.
      --image-repository string              Choose a container registry to pull control plane images from (default "k8s.gcr.io")
      --kubernetes-version string            Choose a specific Kubernetes version for the control plane. (default "stable-1")
      --node-name string                     Specify the node name.
      --pod-network-cidr string              Specify range of IP addresses for the pod network. If set, the control plane will automatically allocate CIDRs for every node.
      --service-cidr string                  Use alternative range of IP address for service VIPs. (default "10.96.0.0/12")
      --service-dns-domain string            Use alternative domain for services, e.g. "myorg.internal". (default "cluster.local")
      --skip-certificate-key-print           Don't print the key used to encrypt the control-plane certificates.
      --skip-phases strings                  List of phases to be skipped
      --skip-token-print                     Skip printing of the default bootstrap token generated by 'kubeadm init'.
      --token string                         The token to use for establishing bidirectional trust between nodes and control-plane nodes. The format is [a-z0-9]{6}\.[a-z0-9]{16} - e.g. abcdef.0123456789abcdef
      --token-ttl duration                   The duration before the token is automatically deleted (e.g. 1s, 2m, 3h). If set to '0', the token will never expire (default 24h0m0s)
      --upload-certs                         Upload control-plane certificates to the kubeadm-certs Secret.

只要执行的时候加上参数就可以了。
kubeadm init --image-repository="imdingtalk" --v=8
